A steerable vehicle has at least one rigid axle carrying steerable wheels, a steering box secured to the axle, and an input rotatable relative to the housing of the steering box with steering control means having first and second relatively rotatable parts, a connection between the first part of the steering control means and the housing of the box having a first element arranged to take up an average position between the first part and the housing during relative rotation therebetween, and a differential gearing between the second part of the control means and the input to the steering box, the differential gearing having a second element which takes up an average position between the second part and input during relative rotation, the first and second elements being connected for simultaneous movement. This prevents steering of the wheels due to relative roll occurring between the steering box and the control means. |
